Problems solved by technology

[0003] In the prior art, the adjustment of the output volume of the electronic device is mainly done manually. When the microphone is used on the electronic device itself and the sound is played through the power amplifier on the device, serious echo interference may be generated and the user experience will be reduced.

Embodiment 1

[0023] figure 1 It is a schematic flowchart of a volume adjustment method provided by Embodiment 1 of the present invention. The method is applicable to the situation of adjusting the volume of the device, and the method can be executed by a volume adjustment device, which can be composed of hardware and / or software, and can generally be integrated into electronic equipment and all terminals including volume adjustment functions. Specifically include the following:

[0024] S110. Receive an ambient sound signal collected by at least one microphone.

[0025] Optionally, ambient sound collection can be performed through a microphone provided on the electronic device, or through multiple external microphones placed at the same location as the loudspeaker of the device and distributed in different directions. Wherein, the microphone can convert the collected ambient sound wave signal into an ambient sound electric signal, and send the ambient sound electric signal to the electro...

Embodiment 2

[0038] figure 2 It is a schematic flowchart of a volume adjustment method provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments, and provides an optimal volume adjustment method, specifically, further optimization is performed on judging whether the current local output sound intensity is lower than the current ambient sound intensity. Specifically include the following:

[0039] S210. Receive an ambient sound signal collected by at least one microphone.

[0040] S220. Determine the current ambient sound intensity according to the ambient sound signal.

[0041] S230. Determine the current output sound intensity of the local machine according to the sound signal output by the local machine.

[0042] S240. Determine whether the current ambient sound intensity is greater than the preset standard sound intensity, if yes, execute S250; if not, execute S270.

[0043] Exemplarily, there is a situation wher...

Abstract

The embodiment of the invention discloses a volume adjustment method and device, an apparatus and a memory medium. The method comprises the steps of receiving an environment sound signal collected byat least one microphone; and adjusting local output volume according to the environment sound signal and a sound signal output by a local, thereby enabling the local output volume is lower than environment volume. Through application of the technical scheme provided by the invention, the echo interference can be improved, and the user experience can be improved.

Description

technical field [0001] The present invention relates to audio technology, in particular to a volume adjustment method, device, equipment and storage medium. Background technique [0002] As an essential part of the sound output function, audio equipment is widely used in various electronic equipment. [0003] In the prior art, the adjustment of the output volume of the electronic device is mainly done manually. When the microphone is used on the electronic device itself and the sound is played through the power amplifier on the device, serious echo interference may be generated and the user experience will be reduced. . Contents of the invention [0004] Embodiments of the present invention provide a volume adjustment method, device, device, and storage medium, so as to improve echo interference and improve user experience. [0005] In a first aspect, an embodiment of the present invention provides a volume adjustment method, including: [0006] receiving ambient sound ...
